GRAPHOPHONE-CABINET.

Specification of Letters Patent.

Patented Feb. 23, 1915.

Application filed July 9, 1914. Serial No. 849.920.

" cabinet body and other elements as to be adjustable to form in effect, a horn or sound intensifier in which the tone volume may be governed by the lid to take the place of shutters, doors and the like, which frequently are employed to control the volume.

The invention provides also a. construc: tion and arrangement to permit of the changing of the needle without the necessity of turning the reproducer relatively to the tone tube.

Other distinguishing features and advantages will appear in the specific description following. 1

Reference isto be had to'the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. I,

Figure 1 is a plan view of my improved cabinet, the lid being removed and the disk and reproducer being indicated; Fig. 2 is a longitudinal pertical section, with the cover in its normal position forming a closure for the cabinet; Fig. 3 is a fragmentary )GISPECtlVQ view of the rear end of the tonetube of the reproducer and its pivot post; Fig. 4: is a perspective view of one form of pivot device that may be employed for mounting the cover; and Fig. 5 is a fragmentary side elevation, partly in section, of a portion of the tone-tube of the reproducer and its pivot post. i

In forming a practicalembodiment of my invention in accordance with the illustrated example, a body 10 is provided, and disposed therein is a transverse partition 11, disposed diagonally and supporting a turntable 12, to be actuated by any approved motor 13, here conventionally indicated. The motor serves to turn the table 12 in its own plane at an angle to the horizontal, determined by the inclination of the partition '11 which constitutes a platform on which the said turn-able turns. Any approved provisionmay be made for retaining a disk record 14 on the turn-table 12. The tone tube 15 carries the usual reproducer which is provided with any suitable means 15 for holding a needle. The tone tube 15 is mounted at one side of the longitudinal center of the cabinet on the platform 11, to swing in a plane parallel with the plane of the turn-table and its platform 11. The rear enlarged end of the rearwardly flaring tone-tube 15 is mounted on a pivot post 16, which may be provided with a foot 16 suitably fastened to the-upper side of the platform 11. The pivot'post 16, it will be seen, is disposed vertically so that it is at an angle less than normal to the plane of movement of the tone-tube and the 3 plane of the platform 11 of the turn-table 19.. The tone-tube is permitted a rockin movement relatively to its general plane o movement. The rear end of the said tube is formed with an upper lug or-arm '17,

20 is. provided, which straddles the pivot fect a closure of the body 10 when the'said cover is in position at the top of" the body, as indicated in full lines in Fig. 2. [The cover 18 displaceable to occupy a position as indicated in dotted lines in Fig. 2. whereby the cover and partition 11 will be in di'veig-" ing planes and constitute in effect, horn elements. The means shown for mounting the cover consists of a depending bracket 'airm at each side having an angular upper end suitablv secured to the under side of the cover. The lower end of each depending arm 22 is formed with an oblique slot. 24 opening from an edge thereof, the slotsbeing adapted to receive pivot pins 25 projecting from the bodv 10 at opposite points oelow the upper edge-otthe body. The slot and pin pivotal connection permits. of the cover being readily removed to afi'ordiready access to the interior. By disposing the pit- (Jo-acting with the partition 11 and the displaceable cover in the formation of horn elements, is a second partition 26 above the partition 11 and rising from the latter. The said partition 26 is deflected rearwardly to a point 26 adjacent to the reproducer, and may terminate at 20, or may have a continuation 26 to the opposite side of the body 10. The upper edge of the partition 96 presents an inclined surface gradually rising from the point 26 at one side of the'longitudinal center and extending to the opposite side of the body, because of the gradually increasing height of the said partition from the point 26 Thus the said upper edge of the partition 26 will conform to the angular position of the cover 21, and the latter will therefore contact with the partition 26, along the upper edge thereof. The front and back of the body may have a layer of felt 27 at the interior. In any case, I will apply felt or the like to the interior of the back, at the upper portion, to cause a tight fit of the cover when closed.

It will be obvious that with the cover in the tilted position and its lower end depressed to a bearing on the partition 26, these elements and the partition 11 will constitute a sound intensifier and form, in effect, horn elements. Moreover,as the cover may be disposed more or less distant from the top of the inclined element 26, to leave a rearward opening between the said element and the cover, and as the cover at the same time is brought more or less close to the front of the cabinet. it follows that the volume of sound emitted at the front of the cabinet may be varied accordingly.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:

1. The combination with a graphophone cabinet comprising a body, and a platform therein arranged transversely and inclined to the horizontal; of means on said platform to support a graphophone record. a reproducer mounted in the cabinet and disposed above the platform, and a cover above the reproducer and platform, said cover being movable to a position to constitute a closure for the top of the body, or to a tilted position with an end thereof depressed within the body and the opposite end above the top of the body, the cover when in the said tilted position, forming with the .fplatform and the cabinet walls, a sound-amplifying passage.

2. he combination with a graphophone cabinet, comprising a body having a transverse platform inclined to the horizontal, of means on said platform constituting a-support for a graphophone record, a movable member presenting a broad surface, and means for supporting said member i, n .an inclined position above the platform and forming with the latter diverging planes, said member, when in the said inclined position, forming with the said platform and the cabinet walls, a sound amplifying passage.

3. A graphophone and cabinet therefor comprising a cabinet body, a transverse platform therein inclined to the horizontal, a turn-table on. the platform adapted to hold a disk record, means for mounting a reproducer to swing above the turn-table in a plane parallel with the latter, a cover, and means to support the cover in position to form a closure for the top of the body, or in an oblique position above the platform to form with. said platform, and the walls of the cabinet, a sound amplifying passage.

4. In a graphophone and cabinet therefor, a cabinet body having a platform below the top of the body inclined to the horizontal and forming the bottom of a chamber of gradually increasing height, means for sup porting a reproducer above said platform at one side of the longitudinal center of the body, a turn-table on the platform, and a cover pivoted intermediate its ends to tilt at an angleto the horizontal and dispose an end of the cover within the body, and a second partition rising from the platform and ranging from that side of the body opposite the supporting means of the reproducer transversely and rearwardly, the upper edge of the second partition being inclined to correspond with the tilted position of the cover.

5. In a graphophone and cabinet therefor, a cabinet body having a chamber, the bottom of which inclines downwardly toward the rear end, means for supporting a record on said bottom, a reproducer above said bottom. a cover for the body, and means to support the cover in tilted position witlrthe said cover and the said bottom disposed in diverging planes and forming, with the walls of the cabinet, a sound amplifying passage.

6. In a granhophone and cabinet therefor, a cabinet body having a chamber, the bottom of which inclines downwardly from front to rear, means for supporting a record and a reproducer in said chamber, and a cover for said chamber pivoted intermedi-. ate its ends to tilt to an inclined position with the rear end depressed within the Said chamber, the cover in the depressed position and the saiki bottom of the chamber presenting diverging planes.

'5'. A graphophone cabinet having a chamher, the bottom of which is inclined to the horizontal, said chamber being adapted to eccomntiodete a record and reproducer, and a cover for said chamber dispiaceablc from a position owning a ciosure of the chamber to a tilted position, the said cover in the tilted position and the bottom of the chamber presenting diverging planes and forming, with the Walls of the cabinet, a sound amplifying passage.
